My Alpine CDA-7863 does not read when I turn the ignition on,the screen does not read,it just make a clicking noise.I have no idea how to manually wire it .I just bought a 1996 tahoe and this Alpine was in it.Some wires were cut so I wired them bak together.the wires are RED,YELLOW,BLACK,BLUE and BLUE with a BLACK stripe.Can some one help?

1. you can go here and get a wiring manual with right model #.http://www.alpine-usa.com/US-en/support/
2. The red wire goes to ignition switch/key.
Yellow wire goes to constant hot/battery.
Black wire is ground.
Blue wire is for power antana you do not need to hook that to anything.
You can look at this diagram for a little more help it is not your radio though but it will give you a reference point to look at. All radio red,yellow,blue,black wires are the same on all radios.http://vault.alpine-usa.com/products/documents/OM_CDA-9884.PDF
go to page 42 on this site for wire diagram.
Good luck with problem.
